Cross beams in ceiling joists
Can these cross beams be removed completely or should they be put back up once i'm done?

These are called bridging. They transfer a load by compression from the top of one joist to the bottom of one on either side. They reduce flexing, (some bouncing of the floor), of one joist at a time so they should go back in.

You also need to look into getting that mold treated that's growing on the joist.

If you pulled them out completely, you may want to buy some metal replacements http://www.strongtie.com/products/co...tb.asp#tables2 as the existing wood cross-bridging (9% effective for deflection) are almost impossible to re-nail at the top of joist, high enough. OR, just add a full size blocking (15% effective) between the removed ones, or add 1x4 strapping to the bottoms (25% effective/deflection)of all after replacing; http://www.ewpa.com/Archive/2004/jun/Paper_278.pdf

Cross beams in ceiling joists
Wow thanks guys for all your responses. Can the cross beams be glued back between the joists?
No there is just a concrete slab. But I am in the process of insulating it very well now(walls, rim joists, ceiling)
I'm putting drywall up in between the joists so can the cross beams be lowered to accommodate the 5/8" drywall?

Those are not cross beams, they are X bracing as previously described. There is no effective way to glue wooden X bracing in place. If you need to get the bracing out of the way to allow installation of drywall, you can install steel X bracing as previously discussed by GBR.

"I'm putting drywall up in between the joists so can the cross beams be lowered to accommodate the 5/8" drywall?"---------- I don't understand. Why would you install drywall above the cross-bridging? Why against the flooring? I must be missing a thought here.....

It's for soundproofing purposes. Drywall and Greenglue against the subflooring. So can they go back up just a little lower 5/8" because of the drywall?

Ahh... Appears you need to shorten a few that flush at the joist bottom. Leave a space between opposing ones so they don't rub/squeak. I usually clip the "air-nails" or "shiners" that miss the joist from above, same reason.
