for example there is a small company with /22 IPv4 allocation from
RIPE in European region. This company is dual-homed and would like to
announce 4x /24 prefixes to both ISPs. Both ISP's update their
prefix-lists automatically based on records in RIPE database. For
example Level3 uses this practice at least in Europe. If this small
company creates a "route" object for it's /22 allocation, then is it
enough? Theoretically this would cover all four /24 networks. Or in
which situation it is useful/needed to have "route" object for each
/24 prefix?

You should create a route object for each route that you announce, if
you announce 4 x /24 you should create a route: object for each /24.

ps. Can you please send 20 dollarcent per /24 to my paypal account
(job () instituut net) with the reference "deaggregation fee"?

Indeed.

Martin, I'd suggest announcing the 4 x /24s to each ISP tagged with the
no-export community in order to achieve whatever you are trying to do,
*in addition* to the covering /22. That way you're not polluting Job,
my, and everyone else's routing tables more than necessary, only your
own ISPs', but then again you're actually paying them for the privilege.
