They were arrested earlier in May during police raids in West Yorkshire, Wiltshire and Wales.
Daniel Wright, 29, Liam Hall, 30, and Stacey Salmon, 28, who are all from Keighley, face charges including possession of articles connected to acts of terrorism.
Samuel Whibley, 28, from Anglesey, is charged with offences including six counts of encouraging terrorism.
They are due to appear at Westminster Magistrates' Court later.
A 16-year-old boy who was arrested in Swindon has been released from custody without charge, it has been confirmed.

The Conservatives have held control of Wiltshire Council.
Although not a surprise in this safe Tory council, they’ve just hit the 50 councillors required to get a majority.
But while they remain by far the largest party, the Liberal Democrat opposition have so far made some locally significant gains in Salisbury, Tisbury, Calne, Trowbridge and Sherston.
Labour so far have held their small contingent of seats in Salisbury but not all declared yet.
The Conservatives' Jonathon Seed is also standing as the police and crime commissioner - the result for that is expected on Monday.
But as BBC Radio Wiltshire's Dan O'Brien reports, he's retained his Melksham Without and West seat for Wiltshire Council.
The BBC's Dan O'Brien has been told by the leader of Wiltshire Council that he will not be seeking re-selection.
The BBC's Dan O'Brien is based in Trowbridge and will bring us the latest from there.
There are also reporters based in Salisbury and Chippenham. You can follow the latest on BBC Sounds.
We're expecting a lot of results today - including from Wiltshire Council.
The votes for the regional West of England mayor, the Bristol mayor and councils in Gloucester and Stroud.
We'll have the latest on this page.

Going to the polls during a pandemic was always going to be a challenge.
But it may be what this election did to local democracy rather than to the nation’s health that it is remembered for.
In three decades of covering elections, I have never seen it so subdued. Uncertainty over whether they would happen did not help.
Then there was an initial bar on parties going leafleting, which sparked complaints, including from Lib Dems in Gloucestershire and Greens in Bristol.
But, the biggest problem was generating interest in local issues.
Normal political point-scoring just did not seem right in the midst of the Covid crisis. And without face-to-face hustings, much of the heat went out of the election.
Instead, it is the global health pandemic, and the success of the national vaccine programme, that was dominant in the news, and in people’s minds, as they voted in these local elections.
