Help Identifying rock or meteorites

[leerace]

I have some rocks wondering if they were meteorites.
Hoping I could get some help Put 2 pictures of each. The first one is magnetic as well as the second one
The second one you can see the lines fold over The third one.
Was not magnetic
But has diamond Lake stones The fourth one looks like it has lines going in 1 direction from like an entry.
And is magnetic the 5 one is magnetic to just not as strong

"Leverite," as in leave her/it right there; veerrryyyy ollddd joke.

Welcome to PF.
Unfortunately, I do not see any meteorites in the collection.

I guess these rocks came from at least two different places. Some are water worn, from a river or a sea shore. It is difficult to identify rocks without being able to get close enough to handle, lick or smell them. A photograph is often insufficient for identification.

The Earth is a big and varied rock collection. It would really help if the latitude and longitude of the finds were recorded, (use Google Earth). That can reduce the possibilities. Also, were they found in an excavation, in a river bed, or on a beach?

What follows is obviously a gross generalisation.

Black, slightly-magnetic rocks tend to be basalts. They may have white minerals deposited by groundwater at the time of the flow. They can also pick up and include local rocks from the river valleys they flow down. Basalts are chemically unstable, reactive, and tend to weather quickly, producing some magnetite, hence the magnetism and red-rust staining.

Black non-magnetic rocks tend to be mudstone, or limestone. They may contain white shell fossils.

Light coloured rocks tend to be sandstones or granites. If they contain vesicles, they may be a volcanic tuff or pumice, that contained gas bubbles when erupted.
Fragile fossils are not well-preserved in sandstones, as they get broken by the high energy environment, then dissolved by groundwater to cement the sand grains.

In addition to what Baluncore wrote, perhaps you can tell us what leads you to suspect these are meteorites anyway?

The first pair of pic's is the only rock that remotely resembles a meteorite
The only killer is that white crystalline stuff I can see on it in the first pic.
ALL the rest are guaranteed Earth rocks .... sandstones and similar

There's no hint of any fusion crust on them
Meteorites of those general sizes would likely to have "flight" features on them
regmaglyphs etc. When I get home from work, I will post some examples from my collection
