Bonsai query

Grandad 99

My wife was given a bonsai kit - seeds, compost, bowl and minimal instructions - for Christmas.

Son-in-law grew one from seed a few years ago and I remember that it involved the seeds going in a fridge at some stage and taking a year to germinate.

My wife's kit  said "wrap the seeds in damp tissue in a cold environment and keep moist. Wait 2-3 weeks until shoots begin to emerge.  Sow seeds in compost with shoot facing upwards"

She started on 5th January, they sprouted after 3 weeks and I've just taken this photo
 Are these really bonsai trees?  If so how should she proceed?  If not any idea what they are and again how to proceed.

Bonsai is a method of training and pruning a tree to produce a tree resembling a miniature version of its normal self.

Bonsai is not a specific species or variety of tree ... so I would pot them on and  follow the instructions ... or what might be even better ... use the internet and library books to learn about the root pruning and wiring, training and pruning of the branches to achieve the style of tree you, or rather your wife wants. 

You’ve got a little while to do some research ... those seedlings aren’t ready for training yet. 

They just need growing on in good light so they grow nice and sturdy and not etiolated by poor light conditions.

Those are Pine tree seedlings so I expect they are Japanese Black pine (Pinus thunbergii), which is often used for growing into a bonsai form.

Here's a link to growing Japanese Black pine as a bonsai, which should help together with Dove's link, above:
