Beginner here..

Welcome to DB.
 

What exercises should be done everyday?

Bodyweight exercises can be performed everyday - pullups, dips, chin-ups, sit ups, push ups.
 

Which exercises should be done every 3-7 days?

Exercises requiring to fight gravity by pushing or pulling an external load can be done every 2 days to every 7 days, depended upon your protein intake, genetic response to stimuli, recovery period, etc.. it all differs between each individual. With that said, your body will adapt to the stress placed on it and recuperate when you allow it to.

What I mean by this is, if you train each muscle group (directly) every 7 days then it'll get used to recuperating every seven days. If you train each muscle group every other day, that's what it'll adapt to. Muscle tissue, according to ACE, repairs to a state of being trained again - depending on factors, in about 48  hours.
 

I'm really interested in strengthening my lowerback, help me.

Squats, deadlifts, power cleans, rows, good standing posture. 
 

Where can I get picture-style examples of the exercises you are suggesting for me?

Video demonstration is on youtube. Google the fitshow for bodybuilding techniques.

Alright, I need some examples of a safe/easy way to get into lifting reguarly.
 
You say, 'depending on factors - every 48 hours' do you mean I should give a muscle group 48 hours then work it again?
 
Are squats and deadlifts the same muscle groups?
 
Should I squats and deadlifts on the same day and then not again for at least two days then?

The amount of time you give your muscle between workout sessions is up to you, I generally do one cycle split (training each muscle group directly once every seven days) then I do a one cycle full body (training each muscle group directly three times per week).

Squats are quad dominant, deadlifts are gluteus maximum dominant. They work similar muscle groups but no, they are not the same. Deadlifts are more taxing to your posterior chain (glutes, hamstrings, lower back) and squats are more taxing to your quads.

You can squat and deadlift on the same day, but you'll generally cheat one more due to loss of ATP levels. Most beginner / intermediate programs that have you squat and deadlift on the same day that require linear increments in intensity will decrease the volume on the deadlifts to keep you progressing in them. Like 3 X 5 for squats, 1 X 5 for deadlifts.

You'll get stronger (noticeably) in your first 2 weeks but won't gain much size, this is because during your first couple weeks of training, your nervous system demands that formerly inactive motor units in your muscle fibers become active, resulting in more overall strength.

Alright.. So Squat on one day, deadlift the next day?
 
I can't get on youtube at work but I'll lookup rows when I get more time.  I've seen/done powerclean before but I'm almost sure I can't find a spotter for it and I don't trust my technique on them.
 
But.. the question is, only do one of those major exercises a day? Then do the little ones I can do everyday and call it a day at the gym?

Alright.. So Squat on one day, deadlift the next day?

You can do that, or  you can just lower the volume of the deadlifts. The routine I gave you has a stiff-leg deadlift, which can be done with just as much volume as squats.
 

I can't get on youtube at work but I'll look up rows when I get more time.  I've seen/done powerclean before but I'm almost sure I can't find a spotter for it and I don't trust my technique on them.

If you do not trust your technique with power cleans, try hamstring curls.
 

But.. the question is, only do one of those major exercises a day? Then do the little ones I can do everyday and call it a day at the gym?

You would do a workout a / workout b, I'll elaborate.

Workout A:
Squat
Stiff-leg deadlift
Flat Bench
BB Row

Workout B:
Squat
Hamstring Curl
OH Press
Pullup

Monday would be "A", Wednesday would be "B", Friday would be "A", then the next week Monday would be "B", Wednesday would be "A", follow me?

As far as pullups / push ups go, it depends on how you do them. If you apply weight, you would want to treat them just like any other movement, but bodyweight movements (meaning you don't apply weight and just do with your bodyweight) can be done every single day. I personally say add weight and just do pullups on pullup days, yet do push ups / sit ups every night.
