You can’t fund more than one of the same within the same tax year.
So you could have all four setup if you really wanted. You just can’t setup and fund say two LISAs this year.
Cash ISA
S&S ISA
LISA
IFISA
The key rule is £20k max spread over all per tax year. (Max of £4k into the LISA per tax year)
So you could open and deposit:
Cash ISA £2k
S&S ISA £14k
LISA £4k
Then in April the counter is reset to another £20k max etc
