It depends on the situation. Personally, I wouldn't use 5w20 instead of 10w30 for a complete oil change. However, using it to top off a quart or two shouldn't be an issue. Oil shears over its life so a little thinner oil shouldn't hurt the engine.
10w30 is thicker than 5w20

That all depends on what weight/grade of oil you need. 5W30, 10W30, 5W20, etc. Around $3.00
5w30 or 10w30

Nothing if they were approved oils. You can mix 10w30 with 5w20 etc. Not a good idea but you can do it. You can mix brands with no problem.
