Need Gm help for first 5e game (Co Gming)

[Nosta]

Hello I'm co Gming a Game with a friend for three of our other friends

I'm going to be taking care of Npc building and such stuff though I need a bit of help

In the first mission it looks like the main GM wants the following

some creatures - 6-8 different ones, probably between CR's 3-6, things you would find in woods/fields/caves. Maybe one or two big boss-esqe ones

If it helps to know the party we have each at level 6

A valor bard
A Artificer not sure the subclass
And A Bard that the GM allowed homebrew stuff for.

So I like a couple of creatures be able to challenge them good

Ok look like artificer is an alchemist

[Jon talks a lot]

Two bards and an alchemist Artificer?

Sounds like a sick party.

A tier 1 big boss might be something like a Hill Giant, perhaps at the end of a naturally made cave that was used as a dungeon.

Ok.

Any other ideas

Ok.

Any other ideas

How about a Green Hag Coven? They would tend to have a variety of other baddies around for support. Ogres, maybe a few undead.

A pair of basilisks could be fun.

Depending on the setting there are dinosaur options.

A green dragon can make a good boss-monster.

A NPC Bard with two Tabaxi Minstrels as understudies.
