Do we have any rules regarding the guild stash? And one of the tab is someone's name, so I'm reluctant to take/put anything.
I also have a ton of skill gems and leveling uniques that would be useful for new players.
I'm not seeing a tab with someone's name on it... maybe that's a parsing error? or are you in hardcore?
I've got 7 showing Harbinger softcore: Gear - Rares - Flasks - Other - Uniques Uno (spanish 1) - Uniques Dos (spanish 2) - Add Only Storage

For the levelling uniques, go ahead and toss 'em in where they'll fit, depending on how much you have to deposit. If that's not enough, ping me here on b12 with a PM and we'll figure something out.
Gems... unless they're special in some way (
drop-only, +quality, or levelled beyond L14) you shouldn't deposit them, or even hold onto them. Between Siosa and Lilly, most gems are easier to simply purchase when you need them.
For general rules on the stash, it boils down to "don't be a jerk." Drop off useful things when you can, grab what you need, but don't make any executive decisions around space use unless there's a proper issue with fullness. With 7 guild tabs we didn't even come close to maxxing out in the front half of Harbinger, when more people were active.
