Can someone identify these two Bell helicopters seen in the Czech Republic?
The mystery has been solved.
Those two helicopters are Agusta-Bell AB 212 operated by Italian Air Force (Aeronautica Militare) coming for Tiger Meet in Poznan, Poland. Their flight route was a little bit confusing because they were VFR flight avoiding CTR.
The more colorful one wears new special tiger paint: https://www.planespotters.net/photo/836257/mm81151-aeronautica-militare-italian-air-force-agusta-bell-ab-212 
The second one seems to wear standard camo: https://1.bp.blogspot.com/-czFFf-7KQyA/Wvu5eNjjgXI/AAAAAAAAMQs/qN9qakgSI9QTmqfosho3Dr6DVmHl-nTNwCLcBGAs/s1600/NTM05.jpg
