Hi Wal
Looks like they are relays (if you mean the big ones) 4 pole by the looks of them without seeing the contact side can't tell if they are CO or NO or NC. You need to know the coil type and resistance the designed operating voltage and current of the contacts. You can start with RS and Farnell. What makes you think they are faulty?
The little ones are just diodes (1N4***) probably

They look like MY4 Relays. There should be identification markings on them, particularly the coil operating voltage which could be something like 6V,12V,24V or 48V. Have another good look at them and note down any printing on the covers.

They are relays, you will need to know the coil voltage before looking for replacements.

OK, these are the marking I can see AP 3441---W or C4-P-DG12v I think that could be DC-------3A250vac 1GD7 or 1GO7 thats all I can make out, on the side you can't see are 4 contacts.

That will be a four pole relay with 3A 250vac contact rating, with a 12v coil.
