1. Trillium erectum
2. Anemone sp.
3. Maianthemum sp.
4. ?
5. Smilacina racemosa

I'm no expert by ANY means so people can correct me if I'm wrong but here's what I see in your pictures:

1. Red Trillium (trillium erectum)

2. Looks like Virginia creeper but those flowers...they aren't as far as I know. Are they separate plants? Or are those flowers attached to the vine? In Virginia creeper the flowers look like this:

3. ?

4. This looks like some sort of "beech". The serrated edges and deeply grooved veins are very beech-like. I think you are right in thinking it's a sapling. And if it's a beech you are fortunate to have it. Take a look around and see if you have any beech trees in the vicinity. The American beech has relatively smooth, silvery grey bark an the branches tend to swoop downward rather than up toward the sky as most trees do.

5. This is either Solomon's Seal

or False Solomon's Seal

The stem of Solomon's seal is quite straight while the stem of False Solomon's seal grows in a bit of a zigzag. Also the flowers on Solomon's Seal are all along the underside of the stem usually in pairs while the flowers for False solomon's seal are at the tip of the stem.

#2 possibly A. quinquefolia
#3 Maianthemum canadense
#4 Viburnum dentatum
#5 Agree with the above but many are calling this Maianthemum racemosa now

For #4 American Elm is also deeply veined and has serrated edges.
Photo for comparison:

It looks very close at any rate.

Keep a little log book or file on your computer of what you find and if you can't identify it, note the features and add a photo if you can until you are able to identify it. It's really quite fun.

#4 is Viburnum dentatum or one of its close relatives like V. rafinesquianum or V. recognitum.

1. stinking benjamin, wake robin
2. Anemone of some kind
3. cow parsnip
4. no clue
5. false solomon seal (or solomon's plume which I like better, that way it's not "false")

I'm no expert, but the leaf on number 4 looks an awful lot like my viburnum dentatum.

See here for a picture.

Clarenancy

3 and 5 are false Solomon's Seal. 4 is a baby ash, I think. 1 is trillium and 2 is Virginia creeper.

Kevin and clarenancy... good call on the viburnum dentatum... just did an image search and your guess looks much better than the three I suggested. Here are some good pics:

Nicely done! :o)
