I have some eucalyptus trees here and wondering who could identify them

I'm sorry Glettol,

Identifying baby Eucalypts is almost impossible.

If the seeds were collected, posting photos of the surrounding Eucalypts including the whole tree and detailed photos of the leaves and bark, also and most importantly the unopened (or opened) seed capsules will help with the ID.

As Kevin says. Not often possible to ID juvenile Eucs. The leaves on seedlings look completely different to the adult foliage. In any case so many Eucs have similar foliage that the only sure way to ID is looking at buds or fruit along with bark type and leaf shape.
Did you germinate these yourself? Do you know where the seed came from? Knowing what trees are in the area can sometimes narrow down the possibilities.
