MAYBE TO SUPPLY CERTAIN LOADS, BUT NOT TO REPLACE THE FULL SUPPLY.

Do you see how much easier the second line is to read? You were requested in your first post to refrain from using ALL CAPS. Besides being more difficult to read, it is considered rude and a form of yelling.
Seriously, if you need more information on your generator installation, you should contact a qualified electrician.
I'll add, single phase power is single phase power. You can't run 3 phase equipment with one phase. So it depends how the house is wired and what runs on 3 phase power.
DEPENDS WHERE YOU ARE. (usual ticking-off for "all caps").
In the UK (and most of Europe), domestic properties are usually fed with 3P+N, but only a single phase and neutral are actually used in any one property. (Sometimes a fault at the local substation will mean that one-third of the houses in a street are blacked out.)
A single phase generator would be fine in most UK and European houses.

You don't mean individual houses have 3 phases do you? I don't think that's the case in UK, split further back between groups of houses, as you say in brackets.
But in Cyprus, or at least the part where a villa I have access to is, all 3 phases come to it, but obviously only one used.

What you do is isolate all three phases from the mains then tie all three together and feed them from the single phase power source. Any larger load devices that draw from two or all three phases will not work but all smaller load devices that only need single phase power will still work just fine.
the two systems are either isolated from each other either by separation or connected by suitable intervening electronics.
